Is there a sample tech form so I can check my car in advance?

Sure, here's a an example Tech Sheet. Note that for some of these items, you need to have some scrutineering knowledge to fully grasp what they're asking for. Also note that all the "state inspection" type of things, like blinkers, lights, horns, and basic roadworthiness of the car, you sign off saying that you have checked those things. Our tech inspectors are looking for the safety items in the rule book.
